Former champion Wyndham Clark has seen his four-shot overnight lead halved as the first round of the US Open concluded early on Friday morning at Shinnecock Hills.
Clark, the 2024 victor and one of four previous winners occupying the top four places heading into round two, parred his remaining two holes after returning at 6.35am local time to sign for a six-under-par 64.
Dustin Johnson, a winner at an equally-tough course in Oakmont in 2016, rolled back the years to post a 66 after he birdied two of his final three holes to move into second place.
